Who gives a rat's arse what the hole looks like under the house where it won't be seen?

I dont care what it looks like on either side of the hole.

But I have to drill from under the house in the crawlspace. Because the side that goes into the garage opens into another really tight crawlspace that I cant get to cause it's too tight.

Basically when you leave the kitchen and go into the laundry room you are leaving the house (stepping over the foundation wall). The laundry room sits on a raised platform in the garage.
The pipe is going to come out underneath the laundry room in the garage.


This is the area under the laundry room. That wall is the one I have to drill through. On the other side of it is the main crawlspace under the house where I'll be drilling from.




That drain line is from my washer. I planned originally just to tap into it, but a plumber suggested not to connect so close to the washer cause it would force water up into the sink. He said to connect closer to the main line. Since the crawlspace is so tight, I'm gonna have to connect on the other side of the wall.

It doesn't look that tight in the pic, but if you look at the blocks you can tell it's only about 1.5 feet high. Too tight for me to get under and work on stuff.


If I was drilling from a outside wall or from one side where I could actually stand up etc. It wouldnt be that hard of a job.

Hey look on the bright side, at least the weather is cooperating and it's not summer with 90+ temperatures and high humidity.

True, bought to go under and get her done. Just gonna drill the hole today. I'll run the pipe next weekend probably

Not the prettiest, but the hole is there. Hardest part ended up being what I was afraid of. Knocking out the backside with a chisel while laying on my side under the house.

The hole on the side I was drilling from came out in a pretty nice circle, but I could get to it with the hammer.

The hole on the backside which you see in the pic .... well it came out. Lol

Didnt take that long really. Took longer getting ready and climbing all the way under the house. It was at the other end of the house than the crawlspace entrance.
